To all whom it may concern.-

Be it known that LPHILo G. BLAIsDELL, a

citizen of the United States, and a resident of Bradford, in the countyof McKean and State of Pennsylvania, have invented certain new anduseful Improvements in Bundle-Tying Machines, of which the following isa specification. My improved bundle tying apparatus is designed moreparticularly for tying bundles of kindling wood with wire bands, but isalso intended for tying bundles of other articles.

In the accompanying drawings, Figure 1 represents my improvedbundletying machine partly in side elevation and partly in sectionalelevation. Fig. 2 is asectional elevation on line 00 0c of Fig. 1. Fig.3 represents part of the machine as seen in, Fig. 1, partly in sideelevation and partly in section, and shows the position of the clincherat the completion of the operation of tying a bundle. Fig. 4 is ahorizontal section on line y y, Fig. 1, showing the parts above saidline inverted; and Fig. 5 is a sectional elevation of the tyingmandreldetached from the rest of the apparatus, with a piece of the tying-wire.It is drawn to a larger scale.

The broken piece a, at the base of Figs. 1 and 2 is to be understood tobe part of a follower on which rests the saucer consisting of two jawsb, in which the pile of wood 0, or other articles is placed to becompressed and tied, said follower being subject to powerful upwardforce to compress the bundle between said saucer and the stationaryyokes d, and hold it while being tied with a wire band e, which is firstlaid in the jaws which are grooved as shown at f, Fig. 2, for receivingit, and then the pieces of wood or other articles to be bundled arepiled in the saucer on the wire. The wire hangs from a spool g, aboveand extends down through the hollow mandrel h, mounted vertically overthe center of the saucer in the horizontal supporting bars 2', j, so asto revolve freely. The bars '5 and j, are supported on the standards 75,set upright in suitable relation to the compressing saucer and yokes. Inthe lower and enlarged head Z of the mandrel is a short longitudinalslot m, extending from the side of said head to the central bore for thewire, and on the end of the head a cam n, is pivoted suitably to gripthe free end of the wire placed in said slot firmly against the side ofthe part of the wire extending out of the mandrel and around the bundle,and hold the two parts of the wire for being twisted together. The'freeend of the wire is to be so placed and gripped in the slot by theattendant when the pile is completed and the bundle has been pressedtogether. The wires are then twisted as at 19, Fig. 2, this beingeffected by means of the sliding handle nut q, arranged to slide down onthe mandrel and having a spurs, or it may be screw threads engaging thespiral groove 25, in the exterior of the mandrel in the well known handdrill contrivance, the parts being so adjusted that one down movement ofthe nut causes the requisite number of turns for completing the twist ofan effective tie. Then the twisted and tied band is to be separated fromthe connected Wire, for which the cutters u are provided, said cuttersbeing formed on the ends of suitably bent levers pivoted at U, to thecross bar '5, and extended upwardly in the diverging prongs w, suitablefor being wedged apart by the lower end of the nut at or about thetermination of the movement of the said nut downward, so as to eifectthe cutting of the wire at or about the upper end of the twist, saidcutters being arranged to take effect on opposite sides of the twistedportion of the two parts of the wire directly below the cam 71. When thehandle nut q is raised again preparatory to the next operation thesprings a open the cutters again. After thus cut-' ting the tie free ofthe connecting wire said tie is to be clinched as shown at b Fig. 3, forwhich the clincher c is provided, said clincher being a kind of hookhead of a sliding bar at on the curved prong e of which the tappet f ofthe handle nut q takes efiect immediately after the operation of thecutters to cause the head of the clincher to thrust forcibly against theside of the twisted tie and bend it down sidewise as shown in Fig. 3,the head being normally at one side of the wires 'of which the twist isformed as shown in Fig. 1, suitably to be forced against and over thetwisted wires as shown in Fig. 3. The reverse movement of the clinchermay be effected by the attendant, or by a spring or other device, Afterthe clinching, the tied bundle is released by descent of the fol- ICOlower and is discharged; The attendant then grasps the lower end of thewire e, which is left as seen in Fig. 3, and pulls the wire down andadjusts it in the jaws of the saucer preparatory to making and tyinganotherbundle. The sliding bar d of the clincher is in this instancerepresented as mounted by the slotted arm f on the studs g for slidingto and fro, but it may be mounted in any other approved way, and I donot limit myself to the form of hook headed clincher shown, nor to thearrangement and manner of operating the cutters, and the gripping camsmay be variously arranged.

I claim- 1. In a bundle tying machine the hollow rotatable mandrelhaving the axial guide for the wire, a cam gripping device at thedelivery end of the mandrel for gripping the two parts of the wiretogether, and means for rotating the mandrel in combination with bundleholding mechanism substantially as described.

2. In a bundle tying machine the hollow rotatable mandrel having theaxial guide for the wire, a cam at the delivery end of the mandrel forgripping the two parts of the wire to be twisted, means for rotating themandrel and cutters for separating the tied bundle from the wire, saidcutters located at the mouth of the wire guide in combination with thebundle holding mechanism substantially as described.

3. In a bundle tying machine the hollow rotatable mandrel having theaxle guide for the wire, means for gripping at the mouth of the wireguide through the mandrel the two parts of the wire to be twisted, thehandle nut for rotating the mandrel, and cutters adapted to beautomatically operated for cutting the wire by the said handle nut foroperating the mandrel, in combination with means for holding the bundlesubstantially as described.

4Q In a bundle tying machine, the combination with bundle holdingmechanism, of the vertical spirally grooved hollow rotatable mandrelhaving the axial guide for the wire, handle nut for operating it, andthe pivoted wire cutters adapted to take effect on the twisted wires atthe mouth of the wire guide of the mandrel, and having the divergentprongs subject to the action of the handle nut for operating them to cutthe wires, directly following the twisting of the wires through theinstrumentality of said nut substantially as described.

5. The combination with the wire feeding and twisting mandrel having theaxial guide for the wire, the operating nut of the mandrel, and with thebundle holding mechanism, of the wire tie clincher adapted to beactuated by the mandrel operating nut substantially as described.

6. The combination with the bundle holding mechanism of the hollowrotatable mandrel having the axial guide for the wire, and the slot inthe end for reception of the free end of the wire, the cam on the end ofthe mandrel for gripping the wires, and the handle nut for operating themandrel substantially as described.
